摘要
对于圆管胶接接头这种几何、材料轴对称结构,在不对称荷载作用下的分析,按经典的有限元方法将是三维的。其复杂性、计算费用、计算机容量的要求将大大增加。鉴于这种情况,本文把单元节点的位移,沿径向、轴向用经典的二维等参数表示,而沿周向的把它展成傅立叶级数。即采用了半解析半有限元的分析方法,有效地把问题简化,在进行一些数据处理后,编写的程序能在微机上运行。
Bonded tubular joint is the axisymmetry structure of geometry, material. Analysis of it on asymmetric load can be displayed by 3-D conventio-nal finite element method with complex, cost of calculation and requirement for big computer capacity.Because of these,in the paper, the element nodal dis-placements are showed in 2-D equal parameter along longitude and latitude,andare displayed in Fourier series along circumference.Using the methods of semi-analysis and semi-finite element,the problems are treated with simplification, then the programmes of it can be operated on micro-computer.
